Never limit your creativity to only what you do professionally.
Always be willing to expand your horizons in every area of your life.
Try a new recipe. Take a new route to work. read a new author. Take up a new hobby. Participate in a new discussion group.
But also use creative techniques to stay physically, mentally, and financially sound. Be open to new ways of doing things.
True creatives live well rounded lives and always seek adventure and intrigue. They know that doing so leads to initiating fresh creative thought more often then just living a ritualistic monotonous life.
